采用根伸长抑制法研究了Zn、Cd、Hg对欧洲云杉幼苗的毒害作用。毒性大小依次为Hg > Cd > Zn。这些金属的水平的比较，示出了在营养液中的根伸长，与那些在林下土壤中表现出枯死的症状，表明在这样的土壤中的金属水平是足够高的影响根的生长。
Inhibition of root elongation was used to assess the toxicity of Zn, Cd and Hg to Picea abies seedlings. The order of toxicity was Hg > Cd > Zn. A comparison of the levels of these metals, shown to inhibt root elongation in nutrient solution, with those in forest soils under stands showing symptoms of die-back, suggests that metal levels in such soils are suffciently high to influence root growth.
